Abstract

The invention provides an interaction log encryption, calling and anti-theft method and device based on a block chain. The method comprises the following steps: splitting biological characteristic information at a terminal; obtaining a corresponding component (the component is a reference characteristic component during registration and the component is a characteristic component during use); then, each component is encrypted by adopting at least one specific encryption mode; the encryption mode of each component is independent; then, the encrypted component is uploaded to the device; according to the method and the device, the split component is obtained through decryption of the device, decryption or matching is carried out by utilizing the split component, so that calling of the interactive log is realized, on one hand, the split mode cannot be stolen, on the other hand, each component is encrypted, and the component is used as a secret key to protect transaction data, so that the security of the interactive log is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of identity authentication, and more specifically, to a blockchain-based interaction log encryption, retrieval, and anti-theft method and device. Background technique [0002] Identity authentication is an effective solution to the process of confirming the operator's identity in a computer network. Biometrics prove your identity based on unique identification characteristics. Biometrics is a comprehensive application or solution for identification, intelligent perception, etc. through the collection and analysis of the inherent physiological or behavioral characteristics of the human body, combined with various high-tech means. Since users do not need to remember passwords and carry media, it is easy to use and is more and more widely used in financial business scenarios such as account opening and payment. Among them, face recognition technology is widely used due to its non-invasive, non-inducti...
